These
injectors allow you to control water flow by means of an external
adjusting knob. This allows the injector to cover a broader
range of flows, taking much of the guesswork out of injector
selection.
They
may be used on either the upstream or downstream side of the
pump. On the upstream side the valve covers a range of .5-3.5
GPM @ 10-120 PSI. On the downstream side the flow rate is
adjustable from 2.0-8 GPM, with a maximum pressure of 3500
PSI. Operating Temperature 180°F.
The
injection rates of these valves are dependent on GPM and pressure,
but range from 6% to 13% on the #7650. The #7655 comes with
a metering barb on the chemical inlet and is adjustable from
0-13%, again dependent on GPM and pressure.
